So Ive been playing a lot of Sin recently and I do like it a lot, but I just unlocked the thunder fury hidden outlaw appearance and was going to do some dungeons with the appearance and went to test out RtB vs SnD on the dummies. Now my gear is a little bit more mastery heavy because I was playing sin and because I believe with SnD Mastery and crit have been top 2 stats for me with vers a little bit behind at 3rd. My stats look something like 31-32% crit 60% mastery 10% vers and like 9% haste.
On the dummies, SnD for me was like 100k+ dps consistent better than RtB even with only sticking with 2 buffs and it definitely feels better for sure.
Also just got Sephuz's secret so that should help a lot too, I really want outlaw to work and even more so SnD but sin is definitely better, was putting up better dps even with my Sin artifact only being like 850 ilvl at the time.
